as serious injury as they did in the case recorded. The writer is 

 informed by those who have seen this larva often before, that it never 

 seriously injures cotton except in some cases where cotton is first 

 planted upon new land. 



GENERAL NOTES. 



SOME INJURIOUS GARDEN AND FIELD INSECTS IN TROPICAL NORTH 



AMERICA. 



August 16, 1903, Mr. O. W. Barrett, entomologist of the Porto 

 Rico Experiment Station, sent specimens of noxious insects from that 

 country which are interesting because of their relation to species 

 known to occur also on the mainland of the United States. One of 

 these was an unknown species of Aphis, which is stated to seriously 

 affect squashes. A leaf -beetle, Cerotoma denticornis 01., very closely 

 related to the bean leaf -beetle of the United States ( Cerotoma trifur- 

 cata), was said to be injurious to cowpeas. A flea-beetle, Systcna- 

 basalts Duv., was injurious to Russian sunflower; while a leaf-hopper, 

 Agallia tenella Ball., was stated to damage the leaves of beans, cow- 

 peas, and other plants. Later, September 30, 1903, Mr. Ed. Ferrer, 

 La Magdalena, Cayamas, Cuba, stated that Cerotoma denticornis did 

 a great deal of harm to cultivated beggar- weed {Meibomia sp.), which 

 also grew wild in that vicinity, from 30 to 50 per cent of the weight 

 of the leaves being a good estimate of what the beetle devoured. 



Diahrotica balteata, another leaf-beetle related to the corn root- 

 worms was received from Mr. A. L. Herrera, City of Mexico, Mexico, 

 with the statement made under date of December 3, 1902, that it was 

 injurious to wheat at Salvatierra, State of Guanajuato. During July, 

 1903, we received from Dr. Silvio Bonansea, of the City of Mexico, a 

 specimen of 8cyj)hophorus acv/punctatus G^^ll . , a weevil quite com- 

 monly occurring in southern California which our correspondent 

 stated was damaging henequen {Agave rigida). A short account of 

 this species and a note on the occurrence of the larva in the interior 

 of the stems of Agave mexicana has been given by Dr. Eug. Duges in 

 the Annales de la Societe Entomologique de Belgique, 1886, p. 33. 

 A short note on the occurrence of the adults on trunks of grape- 

 vine at Poway, Cal., where they feed on sap, was also published, in 

 Volume V of Insect Life (p. 35). 



REMEDY FOR STORED GRAIN INSECTS IN CUBA. 



Mr. Limeon Poveda, jr., owner of a breeding farm in the suburbs 

 of San Leandro, the municipal boundary of the Cuban town of Palma 

 Soriano, known also as San Juan, who is also engaged in the practical 

 study of agriculture, writes as follows in regard to the occurrence of 

 weevils in maize and the remedies to be used in combating them:
